San Diego  The District Attorney’s Office has begun to review the investigation into the death of a San Diego woman who was struck by a car while hiking in Black Mountain Ranch.

San Diego police forwarded their investigation into the crash this week, and it will be up to prosecutors to decide what, if any, charges may be filed against the driver, Lawrence Farry, 25, authorities said Wednesday.

Investigators calculated that Farry was driving 87 mph when he struck Joan Milazzo on Camino del Sur near Paseo del Sur on Aug. 30, according to a police report obtained by The San Diego Union-Tribune.

The posted speed limit for that stretch is 50 mph. Police listed speed as the primary factor for the crash, saying Farry could not slow down in time or control the vehicle because of the excessive speed, the report states.

Farry was not impaired at the time, although he told police he was on his way to work and running about five minutes late when the crash occurred.

Milazzo, 56, was hiking the trails in Black Mountain Ranch in northern San Diego with her husband and sister when the accident occurred shortly before 10 a.m. The trail continues on the other side Camino del Sur, although there is no crosswalk or traffic signal there.

The woman crossed first, and her sister reported seeing the Nissan Altima come at them and appear to lose control before striking Milazzo.

Farry, who lives in Rancho Bernardo, told police he honked his horn and changed lanes while braking in an attempt to avoid the women. He stopped and called 911.

Milazzo died at the hospital.

A call to Farry was not immediately returned Wednesday afternoon.

Milazzo and her husband, Paul, had moved this year to the Del Sur neighborhood from the Los Angeles area to be closer to their grandchild, said her son-in-law, Chris Campbell. She had also recently retired as an account executive at a pharmaceutical company.

“She was so vibrant, so full of life,” Campbell said.

Her family hopes the driver will be held accountable for the death.

“We want to make sure we get justice for Joan,” Campbell said Wednesday.

The family is also petitioning the city for more safety signals in the area, especially where hikers are forced to cross the roadways to pick up trails.
